Products

• Secondary Battery Electrolytes and Additives: We supply electrolytes and additives for lithium-ion secondary batteries, including Lithium bis(fluorosulfonyl)imide (LiFSI), Lithium phosphoryl difluoride (LiPO₂F₂), and Lithium bis(oxalato)borate (LiBOB), to domestic and international electrolyte manufacturers. These products contribute to improving battery ion conductivity, thermal stability, low-temperature performance, and lifespan.
• Separator Binder: We develop and produce separator coatings such as AQC water-based binders, which play a crucial role in preventing separator shrinkage and reducing the risk of battery fires. We contribute to safety improvements by supplying to domestic battery cell manufacturers.
• Optical Coating Paints: We produce UV coating paints, UV blocking coatings, anti-fingerprint and scratch-resistant coatings, and UV-curable pattern resins and adhesives. We provide various coating solutions for electronic devices and industrial applications, including materials for mobile phone view covers.

Special Notes

• Independent Technological Capability and R&D Competence: We possess core technologies for SOL-GEL synthesis and UV-curable formulations, and have established independent manufacturing technology and acquired patents for high-value-added secondary battery materials such as LiFSI. Based on specialized R&D personnel, we are achieving continuous technological innovation.
• Global Market Competitiveness and Growth Potential: We are strengthening our global market competitiveness by expanding supply not only to major domestic electrolyte manufacturers but also to major electrolyte companies in China and India. We have been selected as a 'Growth Company' for the 2025 Global Strong Small Company 1000+ Project and are being nurtured as a leading global strong small company.
• Stable Production Capacity and Quality Management: We have established a mass production base by operating multiple production sites, including our headquarters in the Saemangeum Industrial Complex in Gunsan, Gunsan Plants 1 and 2, and Eumseong Plant. We maintain a strict quality management system through ISO 9001 and ISO 14001 certifications.

Recruitment Information

• Main Hiring Positions: We primarily recruit for positions such as production functional roles (new/experienced), strategic planning team (experienced), finance and accounting team (experienced), and overseas/domestic sales (new/experienced).
• Benefits: We provide support for the four major insurances (National Pension, Employment Insurance, Industrial Accident Compensation Insurance, Health Insurance) and severance pay. We also offer benefits such as dormitory support, health check-ups, support for various congratulatory and condolence events, and work attire support.
